Sorry, Couldn't help but reply.
You really need to do some thinking of your own. Without questioning the conclusions of each of the articles in question, if these are the arguments being used to come to the conclusions, someone needs to go back to school. From the first article regarding the relative size of human impacts, this quote (and it is in context)
"It is true that human emissions of CO2 are small compared with natural sources. But the fact that CO2 levels have remained steady until very recently shows that natural emissions are usually balanced by natural absorptions."
tells me that the author has never seen the Vostock ice core records of CO2 levels.
The article about doing something about climate change is the usual destroy the economy stuff. Given that the article does not differentiate between human caused climate change and natural climate change gives one pause.
The higher level of CO2 doesn't increase plant growth article has these insightful things to say in proving that CO2 doesn't boost plant growth. Again, these are in context. Read the articles if you don't think they are.
"Where water is a limiting factor, all plants could benefit."
and
"These experiments suggest that higher CO2 levels could boost the yields of non-C4 crops by around 13 per cent."
Just to be clear, there is a very strong case that human emissions are significant enough to matter. The article you quote is clueless as to what that case is. Those New Scientist articles are horrible. They are horrible because they are so easily rebutted. If I were a "denier", I would encourage everyone to read them. As Napolean said, never interrupt your enemy when he is making a mistake.
